To all whom it mo'y conc'ern: Be 1t :morm that I, JOHANN GOTTLIEBLnnnnnou'r BORMANN, of 28 Schluterstrasse,

, the generator shaft, While Charlottenburg, near Berlin, Kingdom oflrussia,-Ger1nany, have invented new and useful Improvements inGas-Generatoraof -Which the following is a specification.

The invention relates to those generators in which the production ofcombustible gases is efiected by the admission of the air renuired forcombustion irrto the upper part of the complete gasi- 'fication ofthecoal at the lower end of the generator shaft is effectedby means ofthe introduction of steam. Hitherto in gen crators of this kind theeduction lines through Which the combustible gas formed is conducted outthe generator were made very narrow and arranged in the Walls of the genorator shaft Without any provision for cooling. Hence arose'the drawbackthat these fines readily became choked .up by the ashes and cokeparticles carried along with the gas, and that in particular the insideoutlets of these fines were blocked up by the clinker and colre cakingiirinl y on the hot Walls of the generator shat The subject inatter ofthe present invention is to obviate, this defect by a special form ofthe gas eduction lines and the provision of en intensive cooling arranement of thelower parts of the generator s aft conta ning thegaseduction flues. For this purpose the apertures of egress and theeduction fines for tne combustible gases are made as wide as possibleand are built into a ring-shaped Water boiler which surrounds on allsides the lower part of the generator shaft. In order to avoidtheaccumulation of steam in this Water boiler the top part of the latter ismade to slope-steeply 11 towards a steam collect- .inoreservoir fittedabove; preferably at the ei e. The steam boiler may conveniently bedivided into several ring-shaped parts adapted to the shape of'thegenerator and the eductionflues, which parts have openingsinterconnecting them, and possess such a shape that they penetrate tarint'o they s aces to be cooled or approach themes c osely as ossible sothat an effective cook ing of the latter is insured.

The accompanying drawings are in illustrationof niyinvention, Figure1-be1ng a section, Fig. '2 a longitudinal section along the line AA andFig. 3 a longitudinal section along the line B.B of Fig. 1.

'lhetwatcr boiler 'the steam boiler 11, and the boiler g and passesthelatter. contact with the incandescent fuel is gasihetl The generator (1,has a filling tunnel b above and a grate (2 below. serves tor theintroduction of the required a": for combustion. ln'lmediately beneathgrate and opening out into the latter is n ranged tho lJOX-SlltPdlarge-dimensioned tube 10, which is connected by a p no 7., l", with thesteam collecting chamberoi a st am boiler i. The vertical tube to hasits lower open end immersed in the ash-pf lillcd with Water, so that itis waterwlosd.

The eduction flue i'or tlio'comlmstible gases produced in the generatorlies ring's'isc round the lower part of the g orator immcdiately abovethe grate. it o the collecting iiuc it, which, sun-cu-" steam pipe o,7:, opens out above into the gas eduction pipe 1.

Around the gas eduction flue f lower parts of the generator shaft orering-- shaped Water boiler 51 is fitted. The latter is inconnection withthe water space i the steam boiler'l and consists of an inside and an.

"ml. the

outside ring, which conununicatc with each other by means of connectingapertures 9 projects into the in ide of the generator shaft; its upperpa' l to rise in the form oi a funnel so i steam or Water vapordeveloped by sorption' of heat is conducted upwa constantly filled withWater in all its parts.

Hence the lower parts of the generator shaft lying above tlf'e gratewhich are formed by the Walls of thiswater boiler g, as Well the gaseduction flue f built into this boiler and traversed by watercirculation tubes 0.. boiler, are cooled on all sides by Wat The funnelt, for the fuel replen shmeut, carries at its lower end a valve shutterp, which can bema'de so substantially as to act as a rammingdeviceinorder to remove an interstices or hollow spaces in the layer of fuel.Its motion is regulated by the liftingcontrivance 9'.

' The generator 0 crates as follows: After thelshaft has been. .illedwith fuel and lire has been started, air is admitted ate and the gasdrawn oil at 'Z by suitable means, in conse" quence of which thetemperature of the burning'fuel on the grate is increased and the Waterin the boiler 9 begins to vaporize. The steam thus produced is conductedthrough the piping 7c, 12 and the tube w to the grate The steam comingin the The upper opening c and togetl'ier with the gaseous products ofthe ascertained the nature of my said invention.

and in what manner the same is to be performed, I declare that what Iclaim is; 1. In a gas generator a fuel shaft, having air inlet ports atthe top and a grate arranged adjacent to the lower end thereof, aneduction flue for the gas produced above said grate, a water boilersurrounding the lower part of said shaft and said eductionflue, saidoiler consisting of two ring-shaped members disposed one above theother, and having a ring-slmped slit between them surrounding the lowerend of said shaft and forming the eduction flue. 2.
